Vaginal Health :: Brown Discharge/foul Odor And Increasing Discomfort

Last month, between totally regular, normal periods, I had a watery brown discharge for 2 days. It was foul smelling and very soppy but aside from the smell it seemed like dried blood finally coming down.

This last week I began noticing a foul smell whenever I went to the bathroom. It smelt like fecal matter, so I simply thought it was my bowels giving me a hard time. I was mortified to find out that during intercourse later that day, the foul smell increased. It was emitting from deep within my vagina! My husband politely told me I smelled 'yeasty' but I have had many yeast/BV infections and even PID and nothing compared to this! Furthermore, there is no itching or irritation. I would never have known about the smell if we hadn't engaged in sex.

I took some AZO yeast and medicated with some anti-yeast suppositories but it has been over a week and the smell has only increased. The brown, watery discharge has also come back. It literally smells like a rat crawled up there and died. Furthermore, I am beginning to feel very sore deep inside my vagina, close to my cervix, (almost like the onset of a PID). I did a pregnancy check: I am not pregnant. My husband swears he can 'feel' something rough at the end of my vagina during intercourse. I had a PAP smear/colposcopy 6 months ago and they told me that I was in the clear with regard to HPV (previously I had been on the alert to make sure nothing spread, but the doctors told me they hadn't seen any growth and that I was looking okay).

I've had ovarian cysts before, but they were removed. I've had a lot of women's issues in the past, but nothing this elusive or mystifying (or gross). Even my yeast infections are less smelly with less discharge than this! Help, does this sound like anything? I've looked at possible causes online and there are very few things that meet the criteria of fouls-smelling w/brown discharge with NO irritation and I am at a loss.
